(1) A nanometer is one-thousandth of a micron , which is one millionth of a meter.

(2) Most of these creatures are quite small; from less than a micron in diameter to a few centimeters.

(3) One micron is 1 millionth of a meter, and chips with narrower gaps between transistors can perform more functions faster.

(4) Their lengths vary greatly in a population, with the most common length being about a micron .

(5) While microscopic, the particles are large enough to be measured in microns , or millionths of a meter.

(6) They used computers to design the complex branching of the veins and arteries that ranged from 10 microns to 3 millimetres wide.

(7) The bubbles then expand to a much larger size, about 6,000 microns , or millionths of a meter - large enough to be seen with the unaided eye.

(8) Nanowires are crystals only a few nanometers in diameter but up to several microns in length.

(9) Each ring - composed of polymer chains abandoned as the solvent receded - is several nanometers high and several microns wide.

(10) The tip has a microporosity of less than or equal to 0.22 microns .

(11) The price differential between broader micron wools, used for carpets, and the finer microns , used for luxury clothing, is returning to normal.

(12) Primary fuel filters, once designed to remove 150-micron particles, are now rated for 10 microns .

(13) Most fluid inclusions are small, only a few microns to tens of microns in diameter, but large inclusions visible to the naked eye are known.

(14) The human eye can only see objects as small as about 40 microns, but most oil contaminants are about 5 microns .

(15) At present, inkjet nozzles can achieve resolutions of about 25 microns, compared to the latest die size of 0.13 microns , using silicon.

(16) Plastic shopping bags are currently about 15 microns thick (a micron is a thousandth of a millimetre).

(17) To make fibers up to tens of microns across, scientists must align hundreds of the nanotubes into bundles.

(18) Banning carry bags less than 20 microns or five microns doesn't quite matter because these bags are recyclable.

(19) The reactors range in diameter from about 400 to 60 microns , or millionths of a meter.

(20) There's a thousand microns in a millimetre for reference there.
